NEET Chemistry Periodic Trends MCQ Question
Which of the following elements is expected to have the highest ionization enthalpy, considering periodic trends?
Boron (B)
Carbon (C)
Nitrogen (N)
Oxygen (O)
Correct Answer
Detailed Explanation
According to the periodic trend, ionization enthalpy increases across a period from left to right. Despite this, nitrogen has a half-filled p subshell, making it more stable and having a higher ionization enthalpy than oxygen.
